The five numbers 4, 9, 15, 20, and 27 are placed in the boxes below to make a true statement. What is the sum of the numbers placed in the boxes in the numerators on the left-hand side:
\[9999+9999=999.\]
Can anyone see an easy way to do this?
27/15 + 9/20 ==9 / 4
27 + 9 ==36 - sum of numerators in the LHS.
Thanks
Did you have a logical method or was it just trial and error?
Maybe you just had a computer check all the combinations for you?
Just a simple computer code in C++ and finds it in a flash.
I thought you probably did that.
I am sure there must be a way to nut it out logically with minimal trial and error attempts.
But i expect using C++ is fun and effective :)
